RAKKA User Agreement

  • Version date: September 21, 2026
  • Effective date: September 21, 2026

Welcome to the RAKKA Global website at rakka.dev (the “Global Site”).

株式会社ハルウエ operates the Global Site and RAKKA account service and is the seller responsible for purchases made through the Global Site, including payment, refunds, and contractual obligations to customers. In this Agreement, “RAKKA,” “we,” “us,” and “our” refer to 株式会社ハルウエ unless a provision expressly identifies another party.

上海雷喀科技有限公司 provides brand and intellectual-property licensing, research and development, and commissioned website technical services. 雷喀（绍兴）科技有限公司 manufactures products and, on our behalf, maintains device records and provides warranty, after-sales, and repair services. Neither Chinese company thereby becomes the contracting party for services provided through the Global Site or purchases made through it.

This Agreement applies to your use of the Global Site, your RAKKA account, product purchases, device registration and warranty functions, service requests, after-sales support, and related customer services. A third-party service remains subject to its own terms where those terms are presented to you.

Please read this Agreement and the Privacy Policy before creating an account or using the services. By actively accepting this Agreement when creating an account, you agree to be bound by it. Nothing in this Agreement limits rights that cannot lawfully be excluded or restricted under applicable consumer law.

1. Eligibility

You must have the legal capacity to enter into this Agreement. The Global Site is not intended for children under 16. If you have not reached the age at which you may enter into this Agreement independently under the law where you live, a parent or legal guardian must review and accept it on your behalf and supervise your use of the services.

You may use the services only where doing so is lawful. Availability of the Global Site does not mean that every feature, product, delivery destination, or after-sales option is offered in every country or region.

2. Accounts and authentication

  1. You may create an account using a supported email verification or registration method. Before an account is created, we will present the current User Agreement and Privacy Policy and require an active confirmation.
  2. You must provide accurate information, keep your sign-in credentials secure, and promptly update information that affects our ability to provide the services.
  3. Passwords, email verification codes, passkeys, and other authentication methods are credentials for the same account. Adding a credential does not create ownership of another account with a similar email address or profile.
  4. You are responsible for activity performed through your account unless it results from our failure to provide legally required security. Contact [email protected] promptly if you suspect unauthorized access.
  5. You may not transfer, sell, rent, or share an account in a way that compromises security or misrepresents the person using the service.

3. Devices, warranty, and service requests

  1. Device registration and warranty functions may use a device UUID, serial number, model, configuration, purchase or fulfillment information, and proof produced by the device. Registration does not extend or replace the warranty terms that applied when the product was purchased.
  2. Warranty eligibility and available remedies depend on the product, seller, place and date of purchase, applicable warranty terms, and mandatory law.
  3. You may submit service requests, messages, device information, purchase evidence, shipping information, images, videos, and other relevant attachments. Submit only information that is reasonably necessary for the request and that you are authorized to provide.
  4. If inspection, repair, replacement, return shipping, or another service may involve a charge, we will present the applicable scope, amount, and material conditions before asking you to confirm it.
  5. Estimated response, repair, or delivery times are good-faith estimates rather than guarantees unless applicable law or an express written commitment provides otherwise.

4. Products and orders

The product page and final checkout confirmation identify 株式会社ハルウエ as the seller and state the product, configuration, quantity, price, currency, material delivery conditions, and other conditions relevant to the order. You must review these details before submitting an order. Merely visiting, creating an account, signing in, or placing an item in a cart does not create a purchase contract.

A purchase contract is formed at the point stated in the final checkout confirmation and order acknowledgement. Payment processing alone does not mean that we have accepted an order. If we cannot accept or lawfully fulfill an order, we will cancel it and refund the amount collected.

5. Prices, taxes, and payment

The final checkout confirmation states the product price, shipping charge, taxes collected by us, other charges collected by us, total amount, currency, supported payment method, and payment timing. Unless checkout states otherwise, payment is due when the order is submitted.

Stripe or another disclosed payment provider may authorize or collect payment, process refunds and disputes, and perform fraud checks on our behalf but does not become the seller. We remain responsible for our contractual obligations and for obligations that applicable law places on us when selecting and instructing service providers.

6. Shipping and delivery

Products are shipped from mainland China only to destinations offered at checkout. Import duties, import taxes, customs-clearance charges, and carrier handling charges that are not collected at checkout are the recipient's responsibility, except where applicable law requires otherwise.

The applicable product page or checkout states the estimated dispatch and delivery timing. These are good-faith estimates rather than guaranteed arrival dates unless expressly stated. Delivery remains subject to applicable export, import, sanctions, customs, product, and carrier restrictions.

7. Cancellations, returns, refunds, and product issues

You may cancel an order before the product is handed to the carrier. After handover, we do not offer a voluntary return or exchange merely because you changed your mind, selected the wrong specification, or no longer want the product. This does not restrict a withdrawal, return, conformity, warranty, or other consumer right that cannot lawfully be excluded.

If a mandatory non-defect return right applies, you bear the return shipping and related costs unless applicable law requires otherwise. Where permitted by law, you may be responsible for documented diminished value caused by handling beyond what was necessary to inspect the product.

If a product arrives damaged, is incorrect, or does not conform to the order or product description, contact us. We bear reasonable return costs and, as appropriate, repair or replace the product or provide a refund. Product-specific warranty terms presented at purchase also apply.

Our Commercial Disclosure states the complete sales conditions, return process, refund timing, and payment-dispute process and forms part of this Agreement for purchases made through the Global Site. Product-specific and order-specific conditions shown before submission also apply.

8. Acceptable use

You must not:

  • use the services for unlawful, fraudulent, abusive, or infringing activity;
  • impersonate another person or misrepresent your authority;
  • submit malware, unlawful content, or content unrelated to a service request;
  • interfere with the operation, security, access controls, rate limits, or technical restrictions of the services;
  • attempt to obtain non-public data or access another person's account, device, files, or service requests without authorization; or
  • misuse warranty, repair, refund, replacement, or customer-support processes.

We may take proportionate steps such as requesting verification, restricting an affected function, preserving evidence, removing unlawful content, or suspending an account where reasonably necessary to protect users, RAKKA, or the services. Where appropriate and legally permitted, we will explain the reason and provide a way to contact us. These measures do not remove rights relating to valid purchases, warranties, or pending service matters.

9. Your content

You retain the rights you hold in messages, files, photographs, videos, and other content you submit. You grant us a limited, non-exclusive permission to host, copy, transmit, inspect, and display that content only as reasonably necessary to provide, secure, and improve the requested service, comply with law, and resolve disputes.

You must have the right to submit the content. Do not submit unrelated identity documents, financial credentials, health information, precise location information, or other sensitive material unless we specifically request it and explain why it is necessary.

10. Intellectual property

The Global Site, RAKKA names and marks, product materials, software, firmware, text, images, and designs are owned by RAKKA or the relevant rights holder. Subject to this Agreement, we grant you a limited, revocable, non-transferable right to use the services for their intended personal or internal business purpose.

Open-source software and third-party material remain subject to their applicable licenses. No other right is granted by implication.

11. Service changes and availability

We may update the services for security, maintenance, legal compliance, or product improvement. We will take reasonable steps to minimize disruption and to give notice of a material planned change where appropriate.

We may discontinue a feature, but doing so does not remove obligations or rights that already arose from a valid purchase, warranty, paid service, or accepted service request. Events outside a party's reasonable control are handled under applicable law; they do not automatically excuse obligations that can still reasonably be performed.

12. Disclaimers and liability

We provide the services with reasonable care and skill. To the extent permitted by law, services made available without a separate charge are provided on an “as available” basis, and we do not promise uninterrupted or error-free operation.

Nothing in this Agreement excludes or limits liability that cannot lawfully be excluded or limited, including liability for fraud, willful misconduct, gross negligence where applicable, death or personal injury caused by negligence, or mandatory product and consumer protections.

To the extent a limitation is permitted, neither party is liable for indirect or consequential loss that was not reasonably foreseeable when the relevant obligation arose. This limitation does not reduce remedies available to you under mandatory law.

13. Suspension, closure, and account deletion

You may stop using the services and may request account deletion through [email protected]. We may need to retain limited information to complete an open service request, honor a warranty, meet legal obligations, maintain security records, or resolve a dispute, as described in the Privacy Policy.

We may suspend or close an account for a material or repeated breach of this Agreement, a serious security risk, or a legal requirement. Where reasonably possible and legally permitted, we will give notice and an opportunity to address the issue.

14. Changes to this Agreement

We may update this Agreement when the law, our services, or our operating arrangements change. We will identify the version and effective date and keep the current text available on the Global Site. For a material change that requires renewed agreement, we will provide appropriate notice and request acceptance before the change applies to continued use that depends on it.

An update does not retroactively change the agreed terms of a completed transaction or reduce rights that have already accrued.

15. Governing law and disputes

This Agreement is governed by the laws of Japan, without prejudice to mandatory consumer protections and choice-of-law rights that apply where you live.

Please contact [email protected] first so that we can try to resolve a concern. You may also use any court, regulator, consumer-protection body, mediation process, or other remedy available under applicable law. This Agreement does not require you to waive a forum or remedy that cannot lawfully be waived.

16. Language and contact

This Agreement is available in English and Simplified Chinese. The English version is the governing version to the extent permitted by law. If mandatory law requires the local-language version to control, that law prevails.
